UNITED STATES- BENJAMIN BLAGKMORE, OF AKRON, OHIO RADIATOR Application filed October 6, 1926. Serial No. 189,836.

This invention relatesdzo new and novel improvements in radiators and while the invention is ca able of being adapted to radiators general y, it is particularly intended for use in steam, hot water or vapor heating systeins.

v Objects of the invention are to provide a radiator of simple, durable construction which may be manufactured at a low cost 'and which will be extremely efiicient in use.

A particular object is to provide a chambered radiator body having radiating fins detachably mounted thereon and to provide a new an improved mounting in which the i radiator is made readily accessible whereby the radiator blades may be quickly and conveniently removed, cleaned and replaced.

A further object is to provide a radiator having a chambered body and to provide a pluralit of fins each having a flange proecting om the inner edge thereof at a right angle to the main body of the fin, whereby the flan e will be positioned flat against said body w1th the outer edge thereof in contact with the adjacent fin and to thereby provide a fin which may be provided at a low cost and which will have a relatively large area contacting with the main body of the radiator whereby a relatively large amount of heat will be absorbed by each fin.

An additional object is to provide a radiator having a removable fin provided with spacing flanges on both the outer and-inner edges thereof whereby air passing therethrough will quickly absorb heat from the main body of the radiator.

A still furtherobject is to provide a fin which may be formed of relatively thin sheet metal and which will possess great rigidity and will not be easily bent or displaced.

The above objects are accomplished and additional ends are attained by the novel construction, combination and arrangement of parts hereinafter described and illustrated in the accompanying drawing wherein I have shown a preferred form of the .-invention,

' it .being understood that the invention is capable of various adaptations and that 50 changes and modifications may be made or resort had to substitutions which come within the scope of the appended claims.

In the drawings like numerals of reference are employed to designate like parts as the same may appear in any of the several views and in which Figure. 1- is a perspective view of a radiator constructed in accordance with this invention, the same showing the casing which is adapted to be positioned in a wall and in which the radiator proper is positioned, the same being shown with parts broken away to conserve space.

Figure 3 is a vertical, sectional view taken as indicated by the lines 3-3 of Figure 1,

Figure 4 is a similar sectional view showing the radiator disconnected from the inlet and outlet pipes and swung to a forward position,

Figure 5 is a horizontal, sectional view showing a portion of theradiator body and illustratin themanner of positioning the radiating ns thereon,

Figure 6 is a perspective view, showing the upper portion of one of the fins employed in carrying out this invention.

Figure 7 is a horizontal, sectional view tak'ep as indicated by the lines 7-7 of Figa0 ure v Figure 8 is a fragmentary view showing in horizontal section a ortion of the radiator body with a modified? form of radiating fins positioned thereon.

Fi re 9 is a perspective view of the moditied;z orm of radiating fin disclosed in Figure Proceeding now to a detailed description of the invention with reference to the particular"'ada tation thereof disclosed in the drawings, t e numeral 10 is used generally to denote the main radiator body. The body 10 is referably rectangular in form and is provi ed with a chamber 11. The body 10 is provided in the bottom wall thereof adjacent one end thereof with an inlet opening n which is fitted an inlet pipe 12. The body is likewise 'rovided on the bottom thereof at a point a jacent the other end thereof with an outlet opening in which is fitted an outlet pipe 13. The numeral 14 is used generally to denote the fins employed in carrying outthe invention. Each fin 14 is formed of relatively thin sheet metal having a centrally positioned opening 15 which extends therein from the lower'edge thereof and terminates in spaced relation to the upper Wall thereof.

Each fin 14 is provided around the inner edgethereof with a flange 16 which projects at a right angle to the main body of the fin. The fins 14 are positionel vertically on the body with the said body received in the opening and with the flange 16 positioned flat against the outer surface of said body. The flange 16 is of suflicicnt width to contact with the adjacent fin thereby forming means whereby the fins may be conveniently spaced apart. Each fin is curved along each lateral edge thereof to provide a roll or tube 17 which project-s from the same side of the fin 14 as the flange 16. The roll 17 is arranged to contact with the outer edge of the adjacent fin thereby forming air passages 18 between adjacent fins.

The numeral 19 denotes a casing which is preferably formed of rectangular cross section and is adapted to be positioned in a wall with the forward wall 19 flush with the wall of the room. The casing 19 may be formed to extend to any desired height and is provided in the forward wall thereof, at the bottom thereof, with an opening 20 which forms a cold air inlet passage. The casing 19 is also provided on the forward wall' 19 thereof at the upper end thereof with an opening 21 in which is fitted a shutter frame 22. The numeral 23 denotes a rectangular opening which is formed in the forward wall 19 of the casing 19 at a point spaced upwardly from the opening 20. The opening 23 is provided with a door 24 which is hinged to.the forward face 19 at the bottom of the opening 23, whereby the door may be swung outwardly on a horizontal axis. The door.24 is provided on the inner face thereof at each lateralside thereof with a pair 'of brackets 25, the brackets 25 being spaced apart to receive the main body 10 of the radiator. Each bracket 25 is secured to the end wall of the body 10 by means of the bolts 26 or other suitable fastening means. The arrangement is such that with the door 24 in a closed position, the radiator body 10 will be in an n right position as shown in Figure 3. T e inlet pipe 12 is o eratively connected to a steam inlet pipe 2 by means of the union 28. The outlet pipe 13 is likewise connected to asteam or hot water return pipe by means of the union-30. j.

In the adaptation of the invention shown in the drawings, the opening 21 is provided with a frame 22 in which is mounted pivoted shutters 31. The shutters 31 are connected along the inner edge thereof to a rod 32, one

of the shutters 31 is provided on the forward face thereof with an outwardly projecting arm 33 to which is connected a cord 34. The numeral 35 is used generally to denote eyes which are secured to the forward wall 19 of the casing 19 at a point adjacent each lateral side thereof, the cord 34 is positioned through said eyes with each end thereof depending therefrom whereby the cords may be operated to open and close the shutters 31.

In use, steam," hot vapor or hot water is introduced into the body 10 through the ipe 12, thus heating the body 10. l The heat rom the body 10 is transmitted through the flanges 16 to the fins 14 thereby causing the air in the passage 18 to become heated and to rise and escape through the opening 21. This displacement of air is replaced by cold air through the opening 20 thereby causing a rapid flow of air through the casing 19. In Figure 8 I have shown a modification of the invention in which the fins 14 are provided at the outer edge thereof with a straight flange 17 which projects therefrom in parallel relation to the fins 16. The fins 14 being otherwise identical in construction.

Having thus illustrated my invention and described the same in detail, what I claim as new and desire to secure by Letters Patent 1. In a radiator, a single chambered rectangular body, a plurality of separate fins detachably mounted on said body in arallel spaced relation to each other, each 11 comprising a metal sheet having an opening extending therein from the bottom thereof, said body snugly received in said opening, a flange projecting at a right angle from the inner edge of each fin and extending around saidopening, each flange being positioned flat a ainst the outer face of said body.

2. n a radiator, a single chambered radiator body, fins separately and detachably mounted on said body in parallel spaced relation to each other, each fin comprising a metal sheet having an openin therein from the bottom thereo said opening being of the same cross sectional shape as said body, said body snugly received in said opening, each sheetprovided with a flange which extends around said 0 ening, each flange being positioned flat against the outer face of said body.

3. In a radiator, a unitary chambered radiator body, fins se arately and removably mounted on said bo y in parallel spaced relation to each other, each fin comprising a metal sheet having an openin extending therein from the bottom thereo said body I snugly received in said opening, a flange proectmg at a ri ht angle from the inner edge of each fin and extending around said opening each flange bein positioned-flat a ainst the buter face ofsai body, the outer e go of each flange'contacting with the adjacent fin.

extending 4. In a radiator, a sinfgle chambered radiator body, a plurality o fins each se aratel and movably positioned on said ha y; eac

fin comprising a sheet of metal having an o ening extending therein from the lower e ge thereof, said fins positioned over said body in parallel spaced relation to each other with said body completely filling said openmgs.

5. In a radiator, a chambered radiator body, fins detachably mounted on said body in parallel spaced relation to each other, each fin comprising a metal sheet having an opening extending therein from the bottom thereof, a right angle flange around said opening,
